We help tech companies scale engineering capacity and deliver perfect systems
PROCESS ASSISTANCE
We gratefully respect the business process teams can have and are ready to give you our support combining all the benefits of Cloud solutions, without compromising the way everyday business runs in your company. As a tech company you need to manage source code, build and delivery it to the cloud.
Our custom Serverless solutions allow you to manage all the tasks in a cloud and do sales via a Serverless CRM system, and because this is Serverless, you only ever pay for what you use.
DATA ANALYTICS
Nowadays Data is the fuel of global Economics, so we must respect the way in which we understand and use it. With proper usage of your data, it can become a powerful tool to set your company apart against others.
AWARENESS
We call it awareness because as a business owner you have to be aware of all the risks and bottleneck in your systems. Having all the required skills to do security and resilience audits our mission is to make our awareness super clear.
SERVERLESS
Yes, Serverless is about costs. Have an idea? Ready to do a Proof-of-Concept? But don’t have a big budget - then Serverless is definitely the choice for you. If your business relies on “pay as you go” charges for the customer - then Serverless is your choice. Need resilience, security and scalability out of the box – once again, Serverless is your choice.

An engineering startup hired Perfsys to provision AWS resources, finish a CI /CD workflow, and document the setup of a web app according to best practices.
The team completed the project easily, allowing the company to focus on the core business. The team made a point of updating the company's engineering on their progress at every stage of the project. Thanks to Perfsys the company is in a good place in terms of project maintenance.
The client submitted this review online.
BACKGROUND
Please describe your company and your position there.
I am part of the engineering team for a startup engineering firm with a development presence in the UK providing a niche B2B software solution and we are building out web services to support licensing and provide customer management tools.
OPPORTUNITY / CHALLENGE
For what projects/services did your company hire Perfsys?
We had developed a customer dashboard web app for our new business, which needed a deployment pipeline.
What were your goals for this project?
We needed someone to take on the responsibility of provisioning AWS resources, finishing up a CI /CD workflow, and clearly documenting the setup of web app while following current industry best practices.
SOLUTION
How did you select Perfsys?
We approached a number of individuals and teams and interviewed a selection to identify someone that would be able to both meet the goals and fit in with our team generally.
After a couple of initial calls, we selected to work with Perfsys based on their approachability and domain experience.
Describe the project in detail.
Once we selected Perfsys, they were eager to engage and deep-dive on our needs as a startup.
We worked closely with a project owner to scope out the deliverables - with recommendations on technology and strategy - early on in the project, and milestones were rapidly marked off by both the project owner and his team.
What was the team composition?
Our main interactions were through a single point of contact, though there were named contributions from another developer.
RESULTS & FEEDBACK
Can you share any outcomes from the project that demonstrate progress or success?
The project was completed easily within the expected time-frame, allowing our internal engineering resources to focus on core business decisions while the cloud deployment was taken care of by Perfsys.
How effective was the workflow between your team and theirs?
The workflow was tightly integrated with how we like to operate. Everything was communicated through Slack, with regular updates. Code commits, and build status updates set up to automatically notify the engineering team of progress.
What did you find most impressive about this company?
I was very impressed with the communication and willingness to teach and transfer knowledge so that we were left in a great place to continue maintenance in the future.
Are there any areas for improvement?
None at all!

Perfsys created a cloud-based website and a CodePipeline for building and deploying sources. The team used a range of technologies including AWS S3 and CloudFront, Python, and API Gateway.
Reliable and consistent, Perfsys offers a solid cost-effective maintenance package with built-in alerts. The team is proactive in resolving website errors, ensuring users experience few to no issues. Although they can improve bespoke development, they are trustworthy and provide candid feedback.

BACKGROUND
Please describe your company and your position there.
I am the CTO of Intro, Inc.
OPPORTUNITY / CHALLENGE
For what projects/services did your company hire Perfsys?
We hired Perfsys to create a serverless website and a CodePipeline for building and deploying sources.
What were your goals for this project?
The goal was a cloud-based website that met our requirements.
SOLUTION
How did you select this vendor?
We selected them based on recommendations from our partners.
Describe the project in detail.
They built the website using AWS S3 and AWS CloudFront. The project also required experience in Python, API Gateway, and AWS Lambda.
What was the team composition?
They provided one full-time Python developer, one full-time Javascript frontend developer, and one development operations manager.
RESULTS & FEEDBACK
Can you share any outcomes from the project that demonstrate progress or success?
I trust them. I can go to bed at night and know that I will not wake up in the morning to a user complaint about website or login errors, something I experienced on a weekly basis with my previous agency. I have a very high level of confidence with Perfsys. Their maintenance package includes built-in alerts, none of which have been triggered yet. If something were to go wrong on the Perfsys side, I am confident they will know about it and resolve it before I hear of it from a user.
How effective was the workflow between your team and theirs?
Their development workflow was based on the Agile/SCRUM approach. We had daily sync calls as well as weekly planning meetings.
What did you find most impressive about this company?
Although we may suggest an idea, they will always keep us straight on industry best practices. The maintenance package I pay now is less than the retainer I for the previous agency, who regularly complained that the retainer was not enough to cover the number of hours they worked each month.
Are there any areas for improvement?
They need to be more proactive in creating bespoke elements on the website and in suggesting better enhancements.
